|
|
This setting provides the number of pre-allocated update structures
|
|
that will be used. Dynamic memory allocations are never made. In
|
|
the likely event that we run out of update structures, the graphics
|
|
subsystem will pause and wait for the next structures to be released.

Overhead is 12-bytes per update structure.

|

A single buffer is pre-allocated for rendering updates. This
|
|
setting specifies the maximum in bytes of that update buffer. For
|
|
example, an update buffers of 32 pixels at 32-bits per pixel and
|
|
32-rows would yield a buffer size of 4096.
